Welded pipe quality that stands the test of time
LSAW pipe is a pipe made of strip steel or steel plate, formed and welded. According to different production processes, LSAW pipes can be divided into the following categories:
1, straight seam submerged arc welded pipe: straight seam submerged arc welded pipe (LSAW) is generally made of steel plate as raw material, through different molding processes, using double-sided submerged arc welding, post-welding expansion to form a welded pipe.
2, straight high-frequency welded pipe: is the use of high-frequency alternating current on the surface of the steel plate is heated, quickly reaching the melting point, pressed and molded welded pipe. Compared with resistance welded pipe, high-frequency welded pipe quality is more stable, higher production efficiency, wider range of applications. The price of high frequency welded pipe is slightly higher than resistance welded pipe.

Fundamentally speaking, spiral steel pipe or straight seam steel pipe is a kind of welded tube. Because of their superior performance, these two steel pipes are widely used in various projects. Of course, because the two production processes are different, in actual There is still a big difference in the use process, which directly leads to a big difference in the use range of the two steel pipes.
Compared with spiral steel pipes, the production process of straight seam steel pipes is much simpler. The production process of straight seam steel pipes is mainly divided into two types, one is high frequency welded straight seam steel pipe, and the other is submerged arc welded straight seam steel pipe. It is precisely because of these characteristics that the production process of the straight seam steel pipe is simple, the production efficiency of the straight seam steel pipe is very high, the cost is low, and the development speed is also very rapid.
